Two series of polydentate ,,-ligands containing thiourea fragments attached to a -cresol scaffold, unsymmetrical mono-acylated bis-amines and symmetrical bis-thioureas, are obtained by common experiments. It is observed that the reaction output is strongly dependent on both bis-amine and thiocarbamic chloride substituents. The products are characterized by 1D and 2D NMR spectra in solution and by single crystal XRD. A preliminary study on the coordination abilities of selected products is performed by ITC at around neutral media.
通过常规实验获得了两类多齿配体，一类是连接在对甲酚骨架上含有硫脲片段的配体、不对称单酰化双胺，另一类是对称双硫脲。观察到反应产率强烈依赖于双胺和硫代氨基甲酰氯取代基。产物通过溶液中的一维和二维核磁共振光谱以及单晶X射线衍射进行表征。在接近中性的介质中，通过等温滴定量热法对所选产物的配位能力进行了初步研究。
